I thought maybe you would like the recipe for this, so here goes: While sweet potatoes are cooking (see further along in recipe) cut off the tops of the pumpkins, hollow out cleanly and smear insides with a little softened butter. Put them on a cookie sheet. Preheat your oven to 375 degrees. With an electric mixer (not a food processor) you whip together 4 c. cooked (boil them) and mashed sweet potatoes, 8 oz softened cream cheese, 1/2 c. softened butter, 2 beaten eggs, 1/4 c. packed brown sugar, 2 1/2 Tbsp. dry sherry, and 1/4 tsp. salt. Whip until light. Stir in 3/4 c. chopped walnuts. Fill the pumpkins, sprinkle each with nutmeg, put on the tops, and bake 40 min. until pumpkins feel tender when lightly squeezed.
